#### Literal equation

## What is an example of a literal equation?

A literal equation is one that has several letters or variables. Examples include the area of a circle (A=πr2) and the formula for speed (v=Dt). If the unknown variable is in the denominator, we multiply both sides by the lowest common denominator (LCD) and then continue to solve.

## Why is it called a literal equation?

One of the dictionary definitions of “literal” is “related to or being comprised of letters”, and variables are sometimes referred to as literals. So “solving literal equations” seems to be another way of saying “taking an equation with lots of letters, and solving for one letter in particular.”
